The TEMPUR-Ergo® Extend Power Base houses some of Tempur-Pedic's most premium technologies. From QuietMode™ which gently tilts your mattress to an anti-snore position, to PerfectSeat™ a setting that optimizes the shape of your mattress to offer the most ergonomic support whether your sleeping, working or watching TV. Plug-In to the USB ports found on either side of the Power Base, or unplug and just relax with a four-zone massage feature with three intensities. An easy to use wireless remote, with back lit one-touch preset buttons allows you to make easy adjustments even in the dark. From your remote you can adjust your power base to nearly any positions, with a max head tilt range of 57° and foot raise range of 50°, or select the Zero Gravity preset and relax as the TEMPUR-Ergo® Extend does all the work for you, elevating your head and feet to closely simulate weightlessness and help take pressure off your back.
